Best Angle Grinder Reviews
1. DEWALT DCG413B 20V MAX Angle Grinder
The Dewalt DCG413B is the cordless angle grinder you’ve eagerly awaited. Why’s that?
Because this ferocious fiend for a grinder lays claim to Dewalt’s XR™ technology that delivers blistering corded-like performance and, in some cases, even surpasses its corded counterparts.
The Dewalt DCG413B is a complete party animal for a grinder that boldly barges its way onto the scene with its striking good looks and feature-packed attributes.
But, what’s most impressive is the high-tech brushless motor that produces the kind of power you’d expect from a 13 amp corded angle grinder.
Then again, as a DIYer or contractor, the number one question you should ask yourself when contemplating purchasing the Dewalt DCG413B is do you really need it?
I mean, do you really need a cordless angle grinder that generates 9,000 RPM cutting speed at your disposal? Well, if you’re serious about mastering your craft, the answer would be yes!
Apart from the performance, the structure/design of the DCG413B has some neat little nuances in comparison to other grinders, and DeWalt’s engineering team seems to have heavily focused on ergonomics.
Maneuvering the DCG413B is done with minimal effort as it weighs just 4.7 lbs with a battery fitted. Even though it’s lightweight, you can add the DCG413B to the brink with its 20V MAX battery, as it seems to know no limits.
One must-have safety feature that DeWalt incorporated with the DCG413B is the electric brake system that engages immediately when the trigger is released and stops the wheel in under 1.5 seconds.
On top of that, DeWalt’s E-Clutch system activates within 1/10 of a second whenever a pinch or stall is detected. Likewise, the brake is engaged immediately when the tool senses kickback and the tool shuts itself off.

2. Makita XAG26Z 18V Cordless Angle Grinder
If you’re less budget-constrained and you’re looking for an exceptionally powerful and exceedingly versatile angle grinder, then perhaps the Makita XAG26Z could be the shiny new workhorse you’ve been scouring the internet for.
The Makita XAG26Z is a hybrid model that can accommodate a 4-1/2 inch and 5-inch disc, providing excellent versatility.
Apart from the immense flexibility the XAG04Z delivers, it also possesses a colossal amount of power for a cordless angle grinder with its BL™ brushless motor that generates 8,500 RPM.
Makita also employed a rather complex feature that electronically controls the brushless motor by efficiently regulating the power consumption to dictate the amount of torque and speed the XAG04Z churns out. And is that not enough, you can always adjust the cutting speed via a variable speed switch setting.
As with most cordless angle grinders, the XAG04Z is admittedly on the heavier side when compared to most other models. Granted, 5.8 lbs isn’t a stupendous amount of weight to be swinging around while you’re butchering sections of mild steel for your own amusement, but it’s something you might want to consider with a larger capacity battery fitted to it.
The XAG04Z is also loaded with safety features for overload, over-discharge, and overheating protection. Makita has attached a whole bunch of unique acronyms describing these cool safety features, and while we could run through them all now, you’d really be none the wiser.
All of these electronic protections and safeties work behind the scenes to administer measures of control and modulate essential defenses to reduce potential mechanical failure.
The soft-start feature is one attribute we appreciated about the XAG04Z and is surely worth mentioning. This motor protection feature functionally suppresses the start-up load to help minimize latent strain on the expensive spiral bevel gears.
The final characteristic worth highlighting about the XAG04Z is the wire mesh that has been installed over the air intake ducts. This superb finishing touch by Makita helps prevent dust and other minuscule debris from invading the motor housing and damaging the windings.

Best Angle Grinder Buyer’s Guide
Angle grinders are great for a variety of tasks, from cutting and grinding metal to removing rust or paint from surfaces. But with so many different angle grinders on the market, it can be tough to know which one is right for you.
Angle Grinder Disc Size and Types
The most common disc size is 4.5” and is also the most versatile size for any DIYer or handyman to have on hand.
But that’s not to say that angle grinders can’t be larger; they can be as large as 7 or 9 inches, which are better for deep cuts and for polishing larger areas.
With that in mind, the size of the disc is just one of many important features. You should also consider the disc types that come with the grinder before buying or, at the very least, the disc types that are compatible with the grinder.
These are used to cut through pipes, bolts, rods, rebar, and other hard materials. They are made from abrasive materials like aluminum oxide, zirconia, or silicon carbide.
These are used to grind away excess material, sharpen tools, and remove rust or paint. They can be made from aluminum oxide, ceramic, or silicon carbide.
Diamond-Tipped Cutting Blades
The diamond-tipped teeth give them enough cutting power to be used on tile, granite, concrete, masonry, and so on. They can also be used for both dry and wet cutting.
With sanding pads, you can clean surfaces off old paint. You can also use them for fine sanding or coarse sanding, depending on the abrasiveness of the disc.
Aluminum Oxide Wheels
These are one of the most common types of cutoff discs and can be used on a variety of materials, including wood, plastic, and metal.
Wire brushes, either a cup brush or a wheel brush, are used to remove rust and to remove flaky paint from various metals. The cup brush is used on flat surfaces, while the wheel brush is used on curved surfaces.
Silicon Carbide Discs
These discs are ideal when you’re trying to shape metal. They can help you grind down various excess materials, such as welding.
Motor power is an interesting subject. Power can be expressed in watts, amps, volts, or CFM (cubic feet per minute). Of course, Watt is a unit of electrical power.
As you might know, power is the product of current and voltage (P = IV). Therefore, if you know the current (A) and voltage (V), you already know the power. CFM, PSI, RPM, etc. is a translation of power to real-world usage.
So, instead of telling you this grinder is 800W, a manufacturer might tell you that it translates to 8,000 RPM, for example.
Corded angle grinders have their input power expressed in amperage/current (since we already know the voltage). For pneumatic grinders, manufacturers use CFM and PSI to show what the power rating translates to.
In other cases, you may find that horsepower is also used. For a quick comparison, 1,000W roughly translates to 1.34HP.
Power is very important. Usually, the larger the grinder, the larger the motor, the higher the power. But what’s most important is to match large discs with a high output.
This is one of the ways of ensuring smooth polish and deep cuts with the larger wheels. Another thing to remember is this. The speed will be inversely proportional to the torque for two grinders with the same power rating.
There’s no reason why you shouldn’t want ease of use and comfort when handling a power tool. Therefore, a cordless angle grinder is arguably the best angle grinder from a comfort standpoint.
This type of tool is lighter and easier to work with. There’s no cord that can get in your way, and you’re not restricted in range. Of course, there are other features that make an angle grinder more comfortable to use than others.
For example, if a cordless tool won’t deliver enough power for your application, you should at least look for an ergonomic non-slip grip. You should also look for removable or at least adjustable side handles.
These don’t just make it more comfortable to use the tool, but they will also let you use it in tight spaces. Locking triggers can also make the tool easier to use during continuous operations.
Speed ratings may seem all over the place if you’re unfamiliar with angle grinders. Some might be tempted to believe that the best angle grinders have the highest RPM ratings.
With speeds varying from 000 RPM -500 RPM to 000 RPM – 11 000 RPM and above, there really is a wide range of output speeds, and some of this depends on the tool’s power source.
This couldn’t be further from the truth. You see, speed or the RPM is given by the manufacturer as “no-load speed.” This means that it’s the maximum speed the grinder can put out without a disc installed. These speed ratings are essentially bench tests, so take them with a grain of salt.
What does this mean for you? It means that a smaller angle grinder may look better on paper than a larger model. But it doesn’t mean that under full load, you will be able to get a deeper cut or a better polish than you would from a larger grinder that is more powerful.
When comparing two grinders of the same speed rating, either 500 RPM or 11 000 RPM, you should also look at the power rating of the tool in order to determine the torque.
In the case of equal speeds or variable speed features, the angle grinder with the higher power output will give more torque.
Best Angle Grinder FAQ
If you’re a do-it-yourselfer, then you know that having the right tools is essential to getting the job done right. And when it comes to power tools, an angle grinder is one of the most versatile and handy tools you can have in your arsenal.
How Do You Use An Angle Grinder?
Always hold an angle grinder tool firmly. Your free or non-dominant hand should always hold the side handle, assuming you’re not using a top handle grip.
Like all cutting power tools, always let the disc reach full speed before you bring it into contact with the work surface, especially with a metal grinder.
All angle grinders come with their own user manuals. Therefore, there might be slight differences in how to approach and use them.
Just remember to always cut and grind at the recommended angles to avoid injury. Also, remember to avoid applying too much pressure when cutting. Doing so when grinding could cause an average-quality disc to bend or break.
How Do You Change The Blade On An Angle Grinder?
First, you’ll have to turn off the grinder and remove the power source. This is necessary to avoid accidental power-ups while changing the blade or disc.
You can either remove the blade guard first with a screwdriver or proceed to remove the disc. There might be slight differences in this step, depending on the model of your angle grinder. However, for the most part, this should work on all angle grinders.
Press the spindle-lock button if the grinder has one, and try to lock the disc in place. Keep holding the button down as you’re removing the clamping flange with the special wrench. Remove the disc and replace it with a new one. Be sure to install it in the same way as the old one.
What Can You Do With An Angle Grinder?
An angle grinder can be the ideal tool to grind out loose mortar. You can also use it to cut through concrete and stone or to cut tiles to size. For cutting tile, it’s best to use a dry-cut diamond disc.
When using a cutoff disc, the angle grinder can help you make short work of various metal cutting tasks such as: cutting rebar, wire fencing, rusted bolts, angle iron, and so on. Note that angle grinders can also be fitted with wire brushes.
A wire brush disc or wheel will allow you to remove flaking paint and remove rust. Depending on the type of brush, you can use it for flat areas or uneven surfaces. Last but not least, you can also use an angle grinder equipped with a grinding wheel to repurpose old tools.
Grinding discs can help you sharpen dull blades or dull edges on tools such as shovels, axes, hoes, and others. It’s worth pointing out that this type of work requires skill and care. That’s because this can overheat the blade and affect its sharpness retention.
If you’ve decided on the Dewalt DCG418X1, then you’ve made a good choice. Its superb performance, comfortable design, one-touch guard, and excellent build quality make it a reliable workhorse for any household chore or worksite job.
Finding the right grinder can be tough. But hopefully, with our guidance, you’ve been able to determine which angle grinder is deemed necessary for your needs. Is it vital to buy the most powerful grinder with every imaginable high-end feature? Hell no!
In theory, any one of these corded or battery-powered beastly barbarians will get the job done; that’s why each of them made our list of best angle grinders.
